CULTlVATOR-SHOVEL.

SPECIFICATION forming part of Letters Patent No. 247,658, datedSeptember 2'7, 1881. Application filed July 2, 1881. (No model.)

To all whom it may concern:

Be it known that I, JAMES F. KING, of Aubrey, in the county of Johnsonand State of Kansas, have invented a new and useful Improvement inCultivator-Shovels and I do hereby declare that the following is a full,clear, and exact description of the same, reference being had to theaccompanying drawings, forming part of this specification, in which--Figure 1 is a front view of my improved cultivator-shovel. Fig. 2 is alongitudinal section on line :0 x of Fig. 1. Fig. 3 is a section on liney y of Fig. 1; and Fig. 4 is a similar section, showing the employmentof alap-joint connection between the plow-point and upper plate.

Myinvention relates to improvements in cultivator-shovels; and itconsists in the peculiar construction and arrangement of the parts, ashereinafter more fully set forthand claimed.

In the accompanying drawings, a represents the 7 upper plate of myimproved cultivatorshovel, the lower straight edge, I), of which isbeveled for a purpose hereinafter described.

The plate a, is provided with holes 0 0, through which the ordinarybolts pass which secure the shovel to the standard of the cul tivator.The plate a is also provided with holes dd near its lower end for thepassage of bolts e e, which also pass through holes in asupporting-plate, h, lying under the plate a and projecting below itslower end to support the plow-point. The heads of the bolts 0 e areprovided with conical heads countersunk in the holes 1 d, so. that the.heads of the bolts are flush with the upper face of ,the plate a. Theends of the bolts are riveted to the sup.- porting-plate h, whereby thelatter is securely attached to the lower face of the plate a. A hole, g,is also made in the supporting-plate h, registering with the hole 0 inthe upper plate, for the passage of one of the bolts which secure theplate a to the standard, whereby the supporting-plate is secureddirectly to the standard. By this construction it will be seen that theupper plate, a, and supporting-plate h are securely attached to eachother, and

each is bolted to the standard.

It represents a plow-point, preferably made of steel, of the usual format its lower end. The upper straight edge, l, of the plow-point isbeveled, so as to fit against the beveled edge I) of the plate a.

Instead of con necting the upper plate, a, and plow-point by a beveledjoint, a lap joint, as shown in Fig. 4, may be employed.

at represents a hole made in the plow-point for the passage of ascrew-bolt, 12, having a conical head countersunk in the plow-point, sothat its head will be flush with the upper face of the plowpoint. Thescrew -bolt n also passes through a hole, 0, in the supportingplate h,made angular at its lower end. The screw-bolt n is held in place by anut, 10, on its lower end.

By this construction, it will be seen that the point is securely held inposition by means of its beveled or lap joint connection with the upperplate and the single bolt passing through holes in the plow-point andsupporting-plate, and that when a plow-point is worn or broken it canreadily be removed and a new plow-point substituted for it. It will alsobe seen that in the operation of the shovel the principal strain isborneby the supporting-plate h, which in my construction is secured to theupper plate, a, to the plow-point, and to the standard, and if thesupporting-plate is broken it can readily be removed and anothersubstituted for it.

I am aware of the patents for plow-points granted to S. M. White and I.A. Francis, dated August 13, 1878, No. 206,910; H. O. Beebe, datedJanuary 6, 1880, N 0. 223,309, and H. A. Ridley, dated April 26, 1881,No. 240,766;

and I therefore lay no claim to such construction, my invention beingconfined to the details of construction whereby the upper plate, theplow-point, and the supporting-plate are each made of a separate anddistinct plate, which may be replaced if broken, each plate beingsecured to both the others, and the upper and supporting plates rivetedto each other, and both adapted to be secured by a bolt passing throughboth to the standard of a plow.

Having thus fully described my invention, what I claim as new, anddesire to secure by Letters Patent, is--- The combination, with theupper plate, a, \vnrdly, and hole m, screw-bolt n, and nut 19, havingitslower straightedge, I), beveled downsubstantially as described, and forthe purpose 1o wardly and provided with the holes 0 e d (I, set forth.of the snpportingplate h, riveted to the upper JAMES F KING 5 plate andprojecting below it, and provided with the hole 0 and hole g,registering with \Vitnesses: the lower hole, 0, of the plate a,plow-point 7a, THOMAS 'l. HARRISON, provided with a straight edge, I,beveled up- A. M. YOUNG.
